摘要

The procedure is for obtaining covering using the technique of automatic aerography employs suspensions of nanometric powder or substances obtained by sun-gel. The nanometric powder is prepared chemically and then the suspension is prepared from the nano-particulated powder. Then covering is carried out by automatic aerography. This procedure enables catalytic coverings to be made for the development of electrodes for fuel batteries. For the aerography, an aerograph (1) is used incorporated by a rail (2) which moves following a triangular wave activated by a wave generator (5) assisted by a compressor (4) which generates a projection (5) of Pt on a substrate.
